Electric Vehicles More Useful: Indian American Scientist
"We showed that even after substantial battery degradation, the daily travel needs of most people are still going to be met," Saxena added.
The findings were published online in the Journal of Power Sources. The researchers took into account nearly 160,000 actual driving itineraries from the National Household Travel Survey conducted by the Department of Transportation.
These are 24-hour travel itineraries showing when a car was parked or driving, including both weekend and weekday usage by drivers across the United States.
This data was fed into the team's unique simulation tool -- Vehicle-to-Grid Simulator - that quantifies second-by-second energy use while driving or charging under varying driving conditions.
"It is important to remember that the vast majority of people don't drive more than 40 miles per day on most days.
"And so they have plenty of reserve available to accommodate their normal daily trips even if they lose substantial amounts of battery capacity due to degradation," Saxena concluded.
